* TSSOP-P is a standard TSSOP package with a thermal pad exposure on the bottom of the package.

The APA2020A is a stereo bridge-tied audio poweramplifier in various 24-pin power packages , includ-ing SOP , TSSOP-P. When connecting to a 5V volt-age supply , the APA2020A is capable of delivering1.8W/1.2W of continuous RMS power per channelinto 4Ω/8Ω loads with less than 1% THD+N ,respectively. The APA2020A simplifies design andfrees up board space for other features .

• Stereo Audio Power Amplifier for Notebook Computer

The APA2020A also served well in low-voltageapplications , which provides 800-mW per channelinto 4Ω loads with a 3.3V supply voltage . Both of thedepop circuitry and the thermal shutdown protectioncircuitry are integrated in the APA2020A , that reducespops and clicks noise during power up and whenusing the shutdown or mute modes and protects thechip from being destroyed by over-temperaturefailure.To simplify the audio system design in notebookcomputer applications , the APA2020A combines astereo bridge-tied loads (BTL) mode for speaker driveand a stereo single-end (SE) mode for headphonedrive into a single chip , where both modes are easilyswitched by the SE/BTL input control pin signal . Forpower sensitive applications , the APA2020A alsofeatures a shutdown function which keeps the supplycurrent only 0.5 µA (typ) .
